please answer the following questions A) Use the kinetic molecular theory to explain why gases are more compressible than solids or liquids. B) Does carbon monoxide float in the air or sink to the ground in a house? Justify your answer with proper calculations. The density of normal air at STP is 1.2 g/L. C) Natural magnesium contains three isotopes: Mg-24, Mg-25, and Mg-26. In a sample, 78.70% of the atoms are Mg-24, 10.13% of the atoms are Mg-25, and 11.17% of the atoms are Mg-26. Calculate the average atomic mass of magnesium. D) Titanium dioxide, TiO2, can be used as an abrasive in toothpaste. Calculate the percentage of titanium, by mass, in titanium dioxide.
